Abstract

The nitrite-scavenging and antimutagenic effects of various solvent extracts from different parts of the loquat. were investigated to develope as source of functional food. The nitrite-scavenging and antimutagenic effects of fractions obtained from methanol extract were most highest in ethyl acetate fraction. Ethyl acetate fraction showed better results in the nitrite scavenging activity of 80% in leaf, 81% in seedless fruit, 73% in peel and 63% in seed. The antimutagenic effect showed strong ethyl acetate fraction of 53.1%, 48.3% in leaf and seedless fruit. The antimutagenic effect increased with increasing concentration of ethyl acetate fraction against mutagenicity induced by direct mutagen of IQ in Salmonella typhimurium TA 100. Addition of 2.5 mg and 5 mg of ethyl acetate fraction showed inhibitory effect of 65.5%, 71.2% in leaf and 63.4%, 69.2% in seedless fruit, respectively.

비파 부위별 추출물의 아질산염 소거능 및 항돌연변이 효과를 조사한 결과는 다음과 같다. 추출용매 중 활성이 높게 나타난 메탄올 추출물을 비극성∼극성 용매별로 계통분획한 에칠아세테이트 분획물에서 잎은 80%, 씨를 제거한 과실 81%, 과피 73% 및 종자 63%로 아질산염 소거 효과가 가장 높게 나타났다. 메탄올 추출물의 분획하여 Salmonella typhimurium TA 100에 대한 항돌연변이 효과를 측정한 결과, 잎과 씨를 제거한 과실의 에칠아세테이트 분획물에서 각각 53.1%, 48.3%로 높게 나타났다. 에틸아세테이트 분획물을 농도별로 첨가하여 항돌연변이 효과를 확인한 결과, 잎과 씨를 제거한 과실의 경우 에틸아세테이트 분획물 2.5 mg과 5.0 mg 첨가시 각각 65.5%, 71.2%와 63.4%, 69.2%로 분획물의 농도가 높을수록 항돌연변이 효과가 높게 나타났다.
